[MacOS] Determine Manufacturer of a Mac Book Pro Retina Display

March 16th, 2013 J. ΞPSTΞÏN 9,915

There is a a lot of fuss going around the latest Retina equipped Mac Book Pro’s. Looks like the MBPs can be delivered with either a Samsung display or a Sharp/LG. The problem is: the Sharp/LG displays seems to produce ghosts on the screen. Apple says there might be “image persistance” in some rare cases, but did not admit that it is related to the type of display used. Anyway the Apple discussions forum provides a huge thread.

So if you wanna make sure that you don’t have a Sharp/LG display in your MBP just type this line: ret-mbp2013:~ me$grep \"EDID\" | sed "/[^<]*</s///" | xxd -p -r | strings -6

The answer will appear immediately. The MBPs equipped with Samsung displays will show sth. like this:Color LCD

The devices with Sharp/LG displays will show sth. like this:Color LCD
